Hollywood blockbuster Watchmen and NBC TV series Heroes have topped the list of the most popular illegal downloads via torrent sites over the past 12 months, according to new research from media monitoring firm Big Champagne.
The Warner Bros-produced feature film clocked almost 17 million downloads while Heroes received a whopping 54 million downloads during the surveyed period.
Big Champagne also found that visits to top torrent sites had almost doubled in the past year.
"Millions of television viewers now access free, unauthorised versions of favourite shows at least some of the time," said Eric Garland, chief executive of Big Champagne.
"This is a socially acceptable form of casual piracy - and it is replacing viewing hours."
